The Open Source Software Development Model (OSSDM) is a software development model that has produced a large number of quality software projects such as the Apache Web Server, Mozilla Firefox Web Browser, and MySQL database. Often Open Source Software (OSS) has been developed outside of standard quality assurance practices for software development. This leads to the question what quality assurance practices exist in OSSDM to help ensure software quality? This paper will explore that question.
